Do you ever have dreams of something you are extremely afraid of? :)

For example I am scared to death of the sight of needle in skin, and it has happened a few times in my life that I saw something in a dream like that, not being able to close my eyes! AAAAAAAAAAAAAAAAAAAAAA AAAAHHHHHHHHHHHH!!!!!! !!!!!!!!!!!!! :S:S:S

All the time actually, more so when I was little though.
One of my big fears is the most inevitable, death. If I have a bad dream (and manage to remember it) it tends to involve my mother or our dog dying in some horrific manner.
